- Annoyance
So this just happened. I stopped the array to make some new pools. Upon stop, i noticed my parity drive assignment had reverted back to the old 4TB parity disk that i had replaced, with a 6TB (SAS), a couple weeks back. I had just left the old 4TB in the drive bay, meaning to clear it later.
When i tried to put the 6TB (current) drive back, it shows "All existing data ...will be overwritten" on the parity slot, but the 4TB (old) drive shows parity is ok (and i know it is not).
As a precaution, i am going to physically remove both the current and old parity drives, and install a totally new drive, then let the parity run again. I'm going to assume the data on the array disks is fine and somehow the system got confused with both parity disks still in play.
I will include the diag file after it happened, with the array still stopped, for your assessment if desired...
